WASHING-MACHINE.

SPECIFICATION formingpart of Letters 'Patent No. 245,444, dated August9, 1881.

Application lcd January 29. 1881. (No model.)

To all whom t may concern Be it known that I, GEORGE W. CAMPBELL, ofVinton, in the county of Benton and State of Iowa, have invented anImproved Washing- Machine, of which the following is a specification.

My invention relates to that class of machines represented by Patent No.118,618, issued August 29, 1871, in which sheet-metal bottoms are fixedto the edges of a wooden box to produce a water-tight tub.

It consists in forming continuous grooves in the edges of the sheetmetal to stiffen the same and to inclose a flexible cord and adhesivecement for the purpose of producing more durable water-tight joints andan improved machine,- as hereinafter fully set forth.

Figure 1 ot' my accompanying drawings is a perspective view of myimproved machine. Fig. 2 is a transverse section. Fig. 3 is a detailview, showing a section of the tub. Jointly considered these figuresclearly illustrate the construction and operation of my completeinvention.

A A are the semicircular sides of the tub.

B and B2 are wooden cross-pieces connecting the epds projecting indiverse ways from the top edges of the sides A.

C O are wooden legs fixed to the outside faces of the sides A ininclined positions, so as to meet at the top and to spread at thebottom, as required, to form a wide base and support for the completemachine.

D D are combined metal shaft-bearings and legsockets. They are uniformin size and shape, and each has a shaft-bearing extendingperpendicularly upward from the top edge and longitudinal center of theside A, and consists of a straight back, f, that has uniform iianges 4of extending inward from its edges to form a vertical groove adapted toreceive the end of the metal shaft g, upon which the concave rubber issuspended. Each shaft-bearing thus constructed has a triangular-shapedsocket, h, formed integral with its lower end, adapted to receive andcover the pointed and united ends of the converging legs that are fixedto the sides of the tub. In the offsets of the complete casting formedby the top of. the socket h are ribs t, that serve to strengthenandsupport the shaft-bearings that extend upward from the top edges of thesides of the tub. These combined shaft-bearin gs and leg-sockets areperforated at proper points to admitscrews, by means otl which they aresecurely fastened in their places on the sides of the tub. Theabove-described features, however, are old; but I have illustrated myinvention as applied to a machine of the construction set forth.

J represents a sheet-metal bottom preferably zinc, nailed at its edgesto the bottom edges of the wooden sides and end cross-pieces of the tub.

K (shown clearly in Fig. 3) is a Hexible cord that is covered with paintor other suitable ladhesive cement, and secured on the edges of the woodand under the sheet-metal bottom by means of rows of nails driventhrough the sheet metal-and into the wood on the opposite 'sides of thecord K, to clamp it fast and to bend a groove in the sheet metal toinclose the cement and cord, and thereby produce continuous water-tightjoints along the semicircular edges of the tub. By thus forming a groovein thesheet metal in the act of nailing it fast, or by means of atinners grooving-machine before nailing it fast, the edge of the sheetmetal is stift'eued, and thereby made less liable to warp and springloose from the wood and cause the tub to leak.

The end cross-piece, B2, is set outward relative to the concave bottomof the tub for the purpose of adapting it to receive and support aWringer insuch a position that' the wringer will not interfere with theoperation of the convex rubber m, that is suspended in and detachablyconnected with the tub by means of the shaft-bearing castings D and themetal` rod g.

I am aware that iiexible and elastic packing material has beeninterposed between the metal bottom and wooden side of a tub; but whenthe edge of the sheet metal is flat the elastic packing under it exertsa constant outward pressure and loosens the nails, and consequentlyimpairs thejoints. By my lnanner of forming a continuous groove in theedge of the sheet metal to inclose a round flexible cord and adhesivecement I overcome the difficulty of forming and maintaining water-tightjoints between the sheet-metal bottom andv wooden sides.

TOO

I therefore do not broadly claim the use of pieces ofv a tub, combinediu the manner set flexible puekiugfor thepurposescontemplatedg forth toproduce improved watertight joints, io

but substantially as shown and described. What I claim, und desire tosecure by Let- I J 5 ters Patent, is GEORGE NV. OAMI BELL.
